Maintainer Contact


  • SilverStripe 4.0
  • PostgreSQL 8.3.x or greater must be installed
  • PostgreSQL <8.3.0 may work if T-Search is manually installed
  • Known to work on OS X Leopard, Windows Server 2008 R2 and Linux


  1. Install via composer composer require silverstripe/postgresql or extract the contents so they reside as a postgresql directory inside your SilverStripe project code
  2. Open the installer by browsing to install.php, e.g. http://localhost/silverstripe/install.php
  3. Select PostgreSQL in the database list and enter your database details

Usage Overview

See docs/en for more information about configuring the module.

Known issues

All column and table names must be double-quoted. PostgreSQL automatically lower-cases columns, and your queries will fail if you don't.

Ts_vector columns are not automatically detected by the built-in search filters. That means if you're doing a search through the CMS on a ModelAdmin object, it will use LIKE queries which are very slow. If you're writing your own front-end search system, you can specify the columns to use for search purposes, and you get the full benefits of T-Search.

If you are using unsupported modules, there may be instances of MySQL-specific SQL queries which will need to be made database-agnostic where possible.
